Abstract

1,255,123. Salts of ethylene-1,1-diphosphonic acid. MONSANTO CO. 28 May, 1970 [29 May, 1969], No. 25748/70. Addition to 1,204,967. Heading C2P. A salt of ethylene-1;1-diphosphonic acid is prepared by heating at 300‹ to 500‹ C. a salt of 1 -hydroxyethylidene-1,1-diphosphonic acid containing not more than one acidic hydrogen atom per molecule and agitating the particles at least intermittently during heating. The process is preferably carried out in a fluidized bed and in the substantial absence of oxygen. Salts of 1-hydroxyethylidene- 1,1 -diphosphonic acid are prepared by reacting the acid with an alkaline material using at least 3 equivalents of the alkaline material per mole of acid.
